BTS has recently made their comeback with the main track “N.O.” from their mini album, “O!RUL8,2?.” Before they made their comeback the group had released a trailer to reveal the concept of their comeback. The concept trailer had the group dancing in a mysterious lighted room with policemen coming in with flashlights.

The dance practice took away the set and the outfits to spotlight the choreography that looks more impressive in the simple setting of a dance practice room. Without the camera pans and multiple angles, we can see better the synchronization of the members and the difficult of the dance moves.
